Abstract The main purposes of this paper are to establish some new BrunnMinkowski inequalities for width-integrals of mixed projection bodies and affine surface area of mixed bodies, and get their inverse forms. 2000 Mathematics Subject Classification: 52A40 53A15 46B2

Farmer Involvement In Agro-Ecological Research – The Organic On-Farm Wheat Variety Trials In Hungary

The acreage of organic farming is constantly increasing in Hungary. The cultivation of cereals – and within it – the production of winter wheat is of main importance in organic field crop production. However, it encounters various difficulties. As official post-registration variety trials only exist under conventional farming conditions, ÖMKi started participatory organic on-farm variety tests in 2012, with the involvement of volunteer farmers all over Hungary. In the past seven years, nearly 50 varieties and more than 20 farms have been included in the tests which were conducted with the aim to find the most suitable varieties for high quality organic wheat production and to exclude the inappropriate ones for respective production regions. Our results demonstrate that there is great potential in choosing the varieties best suited, and that it is possible to achieve both high yield and excellent quality also in organic farming, when applying the suitable cultivars

Re-Introduction of Ancient Wheat Cultivars into Organic Agriculture — Emmer and Einkorn Cultivation Experiences under Marginal Conditions

Modern agriculture depends on the production of very few crop species, which provide lower nutritive value for consumers. The present work summarizes the results of a three-year experiment on hulled wheat varieties as potential candidates for food system diversification. The organic field cultivation tests with 10 emmer and five einkorn landraces and varieties were conducted on ~10m2 plots on sandy soil, and from 2017, under on-farm conditions in eastern Hungary. Most accessions adapted well to the marginal conditions, with some landraces even yielding higher than registered varieties—over 3 t per ha on average over three years. Compared to emmer, einkorn had higher maximum grain yields, but its yield performance varied more than that of emmer. Grain protein and the total phenolic content were high in both species. Compared to emmer, einkorn seeds exhibited a 3.8 times higher content of bound flavonoids and had 3.4 times higher antioxidant activity. Four einkorn accessions were resistant to leaf spot, as well as yellow and leaf rusts. Fusarium infected both species similarly. Our findings indicate that not only registered varieties of ancient wheat species but also their landraces can provide sustainable alternatives both for organic farmers and also for the diversification of agriculture
